|---|---|---|---|---|---|
| The branch of Earth Science | Geology
🗑
|
||||
| A principle that states that the same geologic processes shaping the Earth today have been at work throughout Earth's history | Uniformitarianism
🗑
|
||||
| A principal that states that all geologic change occurs suddenly | Catastrophism
🗑
|
||||
| A principal that states that younger rocks lie above older rocks in undisturbed sequences | Superposition
🗑
|
||||
| An ideal sequence of rock layers that contains all known fossils and rock formations on Earth arranged from oldest to youngest | Geologic column
🗑
|
||||
| A break in the Earth's crust along which blocks of the crust slide relative to one another | Fault
🗑
|
||||
| Molten rock from the Earth's interior that squeezes into existing rock and cools | Intrusion
🗑
|
||||
| Occurs when rock layers bend and buckle from Earth's internal forces | Folding
🗑
|
||||
| Occurs when internal forces in the Earth slant rock layers without folding them | Tilting
🗑
|
||||
| A surface that represents a missing part of the geologic column | Unconformity
🗑
|
||||
| Exists where part of a sequence of parallel rock layers is missing | Disconformity
🗑
|
||||
| Exists where sedimentary rock layers lie on top of an eroded surface of non-layered igneous or metamorphic rock | Nonconformity
🗑
|
||||
| Exists between horizontal rock layers and rock layer that have tilted or folded. The tilted or folded layers were eroded before horizontal layers formed above them | Angular unconformity
🗑

🗑
|
||||
| Atoms of the same element that have the same number of protons but have different number of neutrons | Isotopes
🗑
|
||||
| Determining the absolute age of a sample based on the ratio of parent material to daughter material is called... | Radiometric Dating
🗑

||||
| Three types of radiometric dating include: | Uranium-lead method, potassium-argon method and the carbon-14 method
🗑
|
||||
| Any naturally preserved evidence of life | Fossil
🗑
|
||||
| Fossils in rocks, mineral replacement, fossils in amber, mummification, frozen fossils and fossils tar are all examples of what? | Fossils
🗑
|
||||
| Any naturally preserved evidence of an animal's activity is called a... | Trace fossil
🗑
|
||||
| Preserved feces, or dung, from animals | Coprolites
🗑
|
||||
| A cavity in the ground or rock where a plant or animal was buried | Mold
🗑
|
||||
| An object created when sediment fills a mold and becomes rock | Cast
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
